Consider the following script:


<?php
try {
$dbh = new PDO("sqlite::memory:");
} catch(PDOException $e) {
print $e->getMessage();
}

$dbh->query("CREATE TABLE foo(id INT)");
$stmt = $dbh->prepare("INSERT INTO foo VALUES(:value)");
$value = null;
$data = array(1,2,3,4,5);
$stmt->bindParam(":value", $value);

/* ?????? */
try {
foreach($data as $value) {
/* ????? */
}
} catch(PDOException $e) {
/* ??????? */
}

/* ?????? */
?>

What lines of code need to go into the missing places above in order for this script to function properly and insert the data into the database safely?

Please answer through the comments I will make it publish on blog..............
